Freescale i.MX6 On-Chip OTP Controller (OCOTP) device tree bindings
This binding represents the on-chip eFuse OTP controller found on
-i.MX6Q/D, i.MX6DL/S, i.MX6SL, and i.MX6SX SoCs.
+i.MX6Q/D, i.MX6DL/S, i.MX6SL, i.MX6SX and i.MX6UL SoCs.
Required properties:
- compatible: should be one of
"fsl,imx6q-ocotp" (i.MX6Q/D/DL/S),
"fsl,imx6sl-ocotp" (i.MX6SL), or
- "fsl,imx6sx-ocotp" (i.MX6SX), followed by "syscon".
+ "fsl,imx6sx-ocotp" (i.MX6SX),
+ "fsl,imx6ul-ocotp" (i.MX6UL),
+ "fsl,imx7d-ocotp" (i.MX7D/S),
+ followed by "syscon".
- reg: Should contain the register base and length.
- clocks: Should contain a phandle pointing to the gated peripheral clock.
+Optional properties:
+- read-only: disable write access
+
Example:
ocotp: ocotp@021bc000 {
compatible = "fsl,imx6q-ocotp", "syscon";
reg = <0x021bc000 0x4000>;
clocks = <&clks IMX6QDL_CLK_IIM>;
+ read-only;
};
